Ok. I removed it. I'll look into this with greater detail later to figure/close this. :) (Anyway, thanks all for your help. It was greatly appreciated. I passed at the class btw.)

 comment Uses needed to break a substitution cipher (alphabet of 5 symbols, normalized entropy of the source of 2)
Ok. Thanks. :) I get it but care to explain one more thing? Why the entropy of the source is $ log_2 120 + 2N $ instead of $ (log_2 5)N$? How can I get that entropy only knowing the normalized one?

Cool, thanks. Got it. So in the end the answer to the question is 4. none of the above;
